This invention relates to ornamental stove pipe.

Many types of modern stoves are manufactured with an enameled finish forenhancing 5 their appearance. Likewise, stove pipe has been providedwith an enameled finish in order to harmonize with the stove. As thedistance between the smoke outlet of the stove and the flue opening canseldom be met by a combination of l'stove pipe sections of standardlength, it is usually necessary to out one or more pipe sections toeiiect a proper connection. In manufacturing enameled pipe, the pipe isout in standard lengths and then enameled. After the pipe is 15"enameled, it is exceedingly difficult to cut it and even when a cut iselfected a chipped and unsightly end results.

It is the principal object of the present invention to provide anenameled stove pipe construc- 20 tion which can be expeditiouslyassembled to eiifect a proper connection between the smoke outlet of.the stove and a fine opening regardless of the dimension therebetweenwithout the necessity of cutting a pipe section.

In practicing my invention, 1. provide enameled stove pipe sections inlengths which are multiples of one inch. The ends of these sections whenthe stove pipe is assembled are held in abutting relation by theprovision of sleeves which telescope within the ends of the enameledsections.

The fittings are connected to the straight lengths in a similar mannerand by such an arrangement a stove pipe may be expeditiously assembledin any desired length which pipe will present 35 a flush and entirelyenameled exterior surface. The pipe also may be erected in the properlength without the necessity of cutting a straight section to meet therequired dimension.

The invention is exemplified in the following description andillustrated by way of example in the accompanying drawing, in which:

Fig. 1 is a perspective view of a stove with a stove pipe assembled inaccordance with my invention illustrated as connecting the stove to 45the flue opening.

Fig. 2 is an enlarged View of a stove pipe constructed and assembled inaccordance with my invention, the same being illustrated in centrallongitudinal section.

Fig. 3 is a perspective view of the fitting for connecting the stovepipe to the smoke outlet of the stove.

Fig. 4 is a perspective view of one of the sleeves employed to connectthe enameled sections of the stove pipe together.

Referring more particulary to the accompanying drawing, It indicates a.stove having its smoke outlet H connected with a fiue opening 82 bymeans of a, stove pipe i l. The Steve pipe is formed in two rightangularly arranged straight 5 sections l5 and it which are connected byan elbow W.

The stove pipe sections are manufactured by cutting stove pipe enamelingstock into the desired lengths. The exterior surface of these lengths orsections are then enameled and the pipe is ready for use.

In practicing my present invention the stove pipe sections are inlengths which are multiples of one inch. That is to say, the sectionsare formed in one inch lengths, two inch lengths, four inch lengths,sixinch lengths, twelve inch lengths and twenty-four inch lengths.

By using a combination of these sections and proper fittings a stovepipe can be assembled to 0 fit any dimension between the smoke outlet ofa stove and the line opening without the necessity of cutting a, pipesection.

To connect the stove pipe to the stove I have illustrated a fitting iiihaving one end oval in form for fitting the smoke outlet sleeve E9 ofthe stove. The other end of the fitting i8 is of the same exterior andinterior diameter as the stove pipe sections. Fittings such as the elbowll are likewise of the same exterior and interior diameters as the stovepipe sections. The fittings such as the elbow ll or Ts when used and thestove pipe sections are of a uniform diameter throughout their length sothat when they are arranged adjacent and in axial alignment their endswill abut and a stove pipe assembly of smooth flush exterior surfacewill be provided.

If the distance between the upper end of the fitting l8 and the lowerend of the elbow H is such that two standard twenty-four inch lengthswill not fit between the same, a combination of Various lengths may beassembled to exactly fit. Assuming that this dimension is fifty-sixinches, the straight portion It: may be made up of two twenty-four inchlengths and two four inch lengths, one of the latter being interposedbetween the two standard length sections and the other between the elbowand the upper end of the uppermost standard section. If this dimensionbetween the elbow and the fitting I8 is fortynine inches, twotwenty-four inch sections with a one inch section between their ends maybe provided to make up the gap. In other words any dimension between theelbow and the upper end of the fitting l8 may be equalled by a propercomthe smoke outlet sleeve l9.

bination of the various standard lengths which I have provided.

In order to connect the enameled sections, I have provided sleeves suchas illustrated in Fig. 4. These sleeves are formed of black iron and ofan exterior diameter that they may be telescoped into the ends of theenameled sections. The fit between the sleeves and the interior of theenameled sections is preferably a tight fit in order to give the stovepipe when assembled sufiicient rigidity and to tightly hold the sectionswith their ends in abutting relation.

I may prefer to form the enameled sections with a round hole at each endso that after the pipe is assembled a hole may be formed through theadjacent sleeve to permit the insertion of a stove bolt which will actas a keeper to maintain the sections firmly in position.

When short sections, such as one, two and four inch lengths arenecessary, they are slipped on the sleeves to a point mid-way betweenthe ends of the sleeve, then the ends of the sleeve are projected intothe ends of the adjacent sections a distance sufiicient to bring theabutting ends of the sections into contact.

In practicing the invention, the enameling stock is cut into lengthswhich are multiples of one inch, as previously described, and enameled.The fittings are made of similar stock and likewise enameled.

In connecting a stove to a fiue, the length of the stove pipe isdetermined and the proper combination of sections is then selected tomeet this dimension. The fitting I8 is then fitted to The stove pipe isthen assembled by connecting the selected sections and fittings by meansof the sleeves 20. A sleeve 20 may be also utilized for projection intothe flue opening l2 if desired as illustrated in Fig. 2.

By constructing and erecting stove pipe in accordance with my invention,it will not be necessary to cut the enameled sections. The length ofthese sections is such that a combination thereof may be made to fit anydimension between the smoke outlet of the stove and the fiue opening.The manner in which the sections are connected enables a rigid stovepipe to be assembled which presents an entirely enameled exteriorsurface, which surface being smooth and fiush so as to be decorative inappearance. The sleeves 20 also serve to reenforce the pipe which isdesirable because of the weight of enameled stove pipe and its tendencyto sag when assembled in long lengths.

It will also be seen that the entire exposed surface of the pipe will besmooth and of a uniform diameter entirely enameled and therefore ofpleasing appearance.

While I have shown the preferred form of my invention, it is to beunderstood that various changes may be made in its construction by thoseskilled in the art without departing from the spirit of the invention asdefined in the appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. A connecter for the sections of a stove pipe, which sections consistof a normal flexible base having a rigid frangible coating of enamel onthe exterior thereof and are rigid by reason of their coating,comprising a substantially cylindrical fiexible black iron sleevetelescopically and snugly held in one end of each of said sections, saidsleeve being capable of distortion to accommodate itself to theirregularities of the shape of a section when inserted in the latter butwithout distortion of the latter, said sleeve when assembled beingentirely concealed by the ends of adjoining sections.

2. In combination, two Stovepipe sections, each consisting of a normallyflexible base having a rigid frangible coating of enamel on the exteriorthereof and being rigid by reason of such coating, a substantiallycylindrical flexible black iron sleeve telescopically and snugly held inone end of each of said sections, said sleeve being capable ofdistortion to accommodate itself to the irregularities of the shape ofthe sections when inserted therein but without distortion of the latter, said sleeve being entirely concealed by the ends of the abuttingsections.
